H. pylori Definition II seropositivity for Helicobacter pylori
Defined as positive if: two or more of antigen VacA > 100, antigen OMP > 170, antigen GroEL > 80, antigen Catalase > 180, antigen UreA > 130.
The CagA antigen was excluded from the data generated in the 2nd week because of a lab-based handling mistake. Hence, this second definition is available without the CagA antigen.
